Catch up with the sci-fi thriller "Invasion" with 10 rerun episodes, noon to 10 p.m.

ABC

TONIGHT'S MUST-SEE

"Invasion Marathon," noon to 10 p.m., ABC Family. After a superb pilot, ABC's "Invasion" started losing viewers. If you missed a week of the complex plot, you were lost. Catch up now. Reruns of 10 episodes start with the pilot, then jumps to the seventh episode at 1 p.m. and the ninth at 2. From there, episodes run in order. Catch them and you'll be back on track. Strange things keep happening in the Florida swamplands. With a brilliant producer-writer (Shaun Cassidy), great direction (supervised by Thomas Schlamme) and appealing stars (Eddie Cibrian, Kari Matchett, Lisa Sheridan), "Invasion" is worth the effort.

OF NOTE

"The Ten Commandments" (1956), 7 p.m., ABC. ABC is piling up the commandments. Earlier this week, it gave us a new miniseries, starring Dougray Scott as Moses. Now comes this epic movie directed by Cecil B. DeMille and starring Charlton Heston. Some people consider it a classic. I find it well-meaning but sometimes wooden.

"Numb3rs," 7 p.m., CBS. In this rerun, a judge's wife has been killed. Don isn't sure she was the real target. She was driving her husband's car and he was hearing a controversial case.

"CSI: Miami," 8 p.m., CBS. After spending six years in prison for rape, a man is freed with DNA evidence. In this rerun, Horatio tries to find the real rapist.

"Conviction," 8 p.m., NBC. In this rerun, Potter is mugged while trying to talk someone into testifying. Peluso is ready to move in with his girlfriend, then learns she's been cheating.

"Law & Order: Criminal Intent," 9 p.m., NBC. When a young computer worker is killed, suspicion turns to a programmer.

"Back on Campus," 10 and 10:30 p.m., ABC Family. This reality show has parents at college with their kids. In tonight's first episode, Phil Sr. throws himself into extracurricular activities. Kevin tries to rebuild his relationship with his hard-working daughter, Susan. In the second, parents and kids prepare for mid-term exams.
